Question about Dell Dimension 2400 PC Desktop

1 Answer

Internet no longer working, but internal network is fine.

Internet provider is Cable or DSL. The internal network has 1 server computer, 4 workstations, 1 network printer , 1 network photocopier and 1 computer that can access the Internet via wireless router. The workstations can access the server with no problems. The wireless does not access the server. The other computers are connected to a D-Link desktop switch and then connected to a wireless D-Link router with the cable modem. The Internet was working earlier today. Now it will only work in the computer is connected directly to the modem or the router. The computer on the wireless still does not work, but this may be due the distance.

    By what I can understand its seems you haven't reset your wireless router or the modem, seeing as you have a connection just not the wireless part

    did you have a brown-out or power outage?
    have you reset the switch and router?
    do the workstations access the internet thru the server?
    can all the wired units use the printer?
    does the hub bypass the server and connect directly to the router?

    From your description - it is not clear what the problem is.
    Is it possible to draw a network diagram, mentioning the IP address schema used and specifically state what the problem is.

I agree with all the above.. it's definately clear as mud how the network is designed and or funtioning. The machines connected to the wireless d-link router.. are they via cat5 inthe wired ports or wireless ? is the server the machine thats connecting to the switch and wiress router and modem? i'd say reset all switches modems routers and machines.. shut them all down.. then fire the cable modem, then the wireless router then the desktop switch then the server, the workstations and the one lonely wireless.. run "ipconfig /all" on all machines and if they aren't all sharing common ips and access, provide the results here for further investigation.

    Can you please give me a diagram on how the internet works?


    hi, Well in case of diagrams I ll use some images. Internet is a network which comprises a massive amount of Public networks, Inter/Intra/Extra networks, servers-hosts, routers, backbones, cables, satellites with billions of users.
    This diagram shows how an internal network is formed.
    This diagram shows how the users and their computers, companies and organization connect to Internet via ISP backbone. As an example using DSL or Cable Modems.
    This is how a Server serves its users. I assume you know the functionality of Servers, Routers. Diagram
    How a Web server works? Diagram

    For that you need to access your router configuration.
    Connect your router to computer with ethernet cable then you can access it with following link.
    http://192.168.1.1
    or
    http://192.168.0.1
    type user as "admin" and password as "admin" or blank or "password"
    Then you can see configuration page of router .
    Click on WAN settings and set network settings of your internet service provider.If you want ip address from your network then enable DHCP.
    If you want wireless click on wireless and set security as WEP if you want to secure.
    Then save settings and restart router.
    Let me know if you need further assistance.

    Did you already forward port 1723? I guess you have done that. To isolate it, try to bypass the router and setup or establish the VPN session there. If it doesn't work, maybe your ISP doesn't allow port 1723 or it's just the modem.

    I am trying to connect my D-Link router to my PC. I changed providers from DSL to CAble, and now it doesn't work. When I try to hook up the router to the cable modem, I no longer have internet service....


    First, you have to directly attach to the cable modem whichever computer the instal tech used to establish your account. Make sure that connection works. Then re-insert the router and clone the MAC address of the instal computer to the router. Then check your DHCP settings. Make sure it's set to get a new IP from your new provider. You may then have to then release your IP and resubscribe.

    Can't receive my E-Mail


    Depends on the (client) program you are using, but...


    1) Test your WEB Browser (Internet Explorer or Firefox),
    to make sure you can get MSN or Google.

    This tell you if the network and the TCP/IP stack are
    working properly.

    2) If the network is fine, open you email client and check
    your server setting for: POP-3, and SMTP.

    These setting must match those specified by your
    IP service provider.

    Also make sure that the email login and server password
    are correct.

    3) Pay particular attention to the error messages you
    get inside you email client, when it fails to access the
    server. These should give you a clue:

    a) Can't find server / invalid domain name ... etc...
    b) Can't login ... user not authorized...
    c) No network connection ... denied...

    etc...

    4) Server and domain name problems indicate a typo or
    error in your POP3/ SMTP settings. These are sometimes
    changed by the IP provider, so please check with them.
    Also check the port numbers:

    Port 110 = POP3 = Incoming mail server
    Port 25 = SMTP = Outgoing mail server

    are typical, but it really depends on th provider.

    5) If you can't login, the login ID or password are wrong,
    or your provider has closed you account, which they tend
    do to with a nasty deliberation if you owe them money.

    6) If the email program cannot connect to the internet at
    all, but you WEB browser can, then you have a fire wall
    problem.

    Check these firewall, and disable them temporarily,
    to see if it fixes the email problem:

    The Windows Firewall: Control Panel === Windows Firewall
    (disable it)

    Any software firewall you may have installed, such as
    Norton's, AVG antivirus...etc. Disable them too.

    If you use an external router or residential gateway
    to connect to the internet, such as SISCO, CVG, SMC

    Log into the router using your WEB browser, and disable the
    firewall.

    7) Once you identify a firewall problem, you need to setup
    exceptions for your email client.

    8) If you cannot get any Internet, including the WEB,
    then you have a different problem.

    a) run the Windows Network setup wizard again,
    from the control panel.

    b) If you connect directly to the Internet through your cable
    or DSL this should fix it.

    c) If you still use a telephone modem, that has to be
    setup as well.

    d) If you use a residential gateway, barricade or router
    to connect to DSL or CABLE, then you need to set
    that up next using you WEB browser. Typical router
    address is: 192.168.1.1

    e) In the case of DSL you router may also need to be
    programmed with you login/password info, because in
    this case it is the router that connects and logs into
    your internet provider's server, not your computer.
    (your computer sees the router, not the provider.)

    Anyway, not knowing what your exact problem is,
    I think that I have covered the waterfront here,
    hope it helps.

    How To Set Up PPPoE DSL Connections with a Linksys Router


    This article describes how to manually configure a Linksys Router for broadband DSL that uses PPPoE (Point-to-Point Protocol over Ethernet) for authentication. For automatic configuration options, please try: 1. Linksys Easy Connect (see Answer ID 1650 for more information), or 2. The Linksys Setup Wizard CD-ROM software that came with your Linksys Router. Simply insert this CD-ROM into an online computer before connecting your Linksys Router, and the Wizard will provide step-by-step instructions on how to install and configure your router. If you are unable to set up your Linksys Router by using one of the above options, use the steps below to manually configure your router. NOTE: It is recommended that you print this article for offline reference. STEP 1: Before You Begin In order to set up your Linksys Router, be sure to first have the following: 1. A Linksys Router. 2. A DSL modem. 3. A working computer that can be wired in directly to the router for initial configuration and testing. 4. Two (2) standard Ethernet network cables. Linksys Routers come with one (1) standard network cable that you can use. 5. The PPPoE DSL username and password assigned by your Internet Service Provider. Depending on the provider, your username format might be similar to username, vzn123456, or an e-mail address (username@isp.net). If you are not sure what your username and password are, contact your Internet Service Provider for more information. STEP 2: Check Your Internet Connection Before installing your Linksys Router, it is important to first verify that you can successfully access the Internet by connecting directly to your modem (without your Linksys Router installed). 1. If you are connecting for the first time, follow the instructions provided by your provider to set up your modem and computer for online access. 2. Verify that you are able to access the Internet without any problems. If you are not able to get a connection, contact your Internet Service Provider for assistance. When you are able to access the Internet using your modem, continue to Step 3 and proceed with the installation of your Linksys Router. STEP 3: Connect the Hardware Follow these steps to connect your Linksys Router to your modem and computer. 1. Shut down your computer and unplug the power cords connected to your modem and Linksys Router if they are currently powered on. 2. Disconnect the network cable that connects to the back of your computer. 3. Connect the network cable that you just removed to the Internet port (or WAN port) located on the back of your Linksys Router. Your modem should now be connected to your Linksys Router. 4. Connect a second network cable back into your computer (into the same port that was disconnected in #2). 5. Connect the other end of the second network cable to one of the numbered ports located on the back of your Linksys Router (labeled 1, 2, 3, 4, etc.). Your computer should now be connected to your Linksys Router. The following diagram shows how your network should be connected. Verify that your connections are correct, and continue to the next step. 6. Plug the included power adapter into the router?s Power port. Then, plug the other end of the power adapter into a nearby electrical outlet to supply power to your router. 7. Turn on your computer. Do not turn on your modem at this time. Only your router and computer should be turned on for Step 4. STEP 4: Configure the Router Follow these steps to configure your Linksys Router. 1. On the computer that is connected to the Linksys Router, open a web browser such as Internet Explorer or Netscape. 2. Type http://192.168.1.1 into your browser?s Address or Location bar and click Go or press the [Enter] key on your keyboard. The IP address 192.168.1.1 is the default IP address of Linksys Routers. 3. A user name and password prompt will appear. Leave the user name field blank (empty), and type in admin (lowercase) for the password. The password admin is the default password of Linksys Routers. NOTE: The following username/password prompt screen will vary by operating system. 4. Once logged in, the router?s web-based Setup utility should load. In the section labeled Internet Connection Type, or WAN Connection Type depending on router model and firmware version, select the PPPoE option on the drop down list. Click here to view what an older Linksys router interface looks like. 5. Once PPPoE is selected, enter your PPPoE DSL username and password provided by your Internet Service Provider into the router?s User Name and Password fields. Depending on the provider, your username format might be similar to username, vzn123456, or an e-mail address (username@isp.net). If you are not sure what your username and password are, contact your Internet Service Provider for more information. NOTE: Be sure to
